Tomcat : Illegal access: this web application instance has been stopped already

Bonjour à tous,

J'ai obtenu les informations suivants quand je démarre mon application. Je ne comprends rien du tout d'où viennent les erreurs et comment résoudre tous ça.:cry:

Quelqu'un a une idée pour ça.


9 oct. 2010 16:47:29 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
GRAVE: The web application [/GDT2] registered the JBDC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
9 oct. 2010 16:47:29 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
GRAVE: The web application [/GDT2] appears to have started a thread named [Session Monitor] but has failed to stop it. This is very likely to create a memory leak.
9 oct. 2010 16:47:29 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
GRAVE: The web application [/GDT2] appears to have started a thread named [MySQL Statement Cancellation Timer] but has failed to stop it. This is very likely to create a memory leak.
9 oct. 2010 16:47:29 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
GRAVE: The web application [/GDT2] created a ThreadLocal with key of type [java.lang.InheritableThreadLocal] (value [java.lang.InheritableThreadLocal@2d73b676]) and a value of type [com.icesoft.faces.webapp.xmlhttp.PersistentFacesState] (value [com.icesoft.faces.webapp.xmlhttp.PersistentFacesState@7d0144a]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.

INFO: Illegal access: this web application instance has been stopped already. Could not load com.mysql.jdbc.profiler.ProfilerEventHandlerFactory. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.
